Upgrade WiFi MD 4/25


WiFi electronic board for MD 4/25 cycling trainer (with BT4 electronic parts – previous versions are not upgradable). The pack includes the replacement and assembly instructions.

The new board includes the WiFi module, which allows the connection and control of cycling trainer through the MD WiFi App.

Model MD series AC/AD/BA MD series AB

The price depends on the model of the trainer. To check which model you have, refer to the last two letters of the trainer’s Serial Number (find out where to check out the SN).

* The upgrade of the AB series models requires a specialized technical assistance, for this reason it’s necessary that the customer sends the smart trainer to the company. Our technical staff will upgrade the motherboard and engine card, and will send the updated product back to the customer. In this case the shipping fees are totally included in the price of the service.


From August 1, 2019, the MagneticDays app (with Bluetooth connection) is no longer available for download from the App Store and Google Play Store.

For this reason, the new owners of the MD 4/25 models with an outdated electronic board (without WiFi module) will have to do the upgrade, so that they can control the trainer from the mobile with the MD WiFi app.
